Abstract

A light detection and ranging (LIDAR) system includes a transmitter, a receiving pixel, a rotating mirror, and a beam displacement apparatus. The transmitter is configured to emit a transmit beam. The receiving pixel is configured to receive a returning beam. The rotating mirror is configured to direct the transmit beam to a target and direct the returning beam to the receiving pixel. The beam displacement apparatus is disposed between the receiving pixel and the rotating mirror. The beam displacement apparatus is configured to introduce a displacement to the returning beam to compensate for a spacing between the transmitter and the receiving pixel.
